Group prenatal care and perinatal outcomes: a randomized controlled trial

Randomized controlled trial and economic evaluation of nurse-led group support for young mothers during pregnancy and the first year postpartum versus usual care

Background

Child maltreatment is a significant public health problem. Group Family Nurse Partnership (gFNP) is a new intervention for young, expectant mothers implemented successfully in pilot studies. This study was designed to determine the effectiveness and cost-effectiveness of gFNP in reducing risk factors for maltreatment with a potentially vulnerable population.

Methods

A multi-site, randomized controlled, parallel-arm trial and prospective economic evaluation was conducted, with allocation via remote randomization (minimization by site, maternal age group) to gFNP or usual care. Participants were expectant mothers aged below 20 years with at least one live birth, or aged 20–24 years with no live births and with low educational qualifications. Data from maternal interviews at baseline and when infants were 2, 6 and 12 months, and video-recording at 12 months, were collected by researchers blind to allocation. Cost information came from weekly logs completed by gFNP family nurses and other service delivery data reported by participants. Primary outcomes measured at 12 months were parenting attitudes (Adult-Adolescent Parenting Index, AAPI-2) and maternal sensitivity (CARE Index). The economic evaluation was conducted from a UK NHS and personal social services perspective with cost-effectiveness expressed in terms of incremental cost per quality-adjusted life year (QALY) gained. The main analyses were intention-to-treat with additional complier average causal effects (CACE) analyses.

Results

Between August 2013 and September 2014, 492 names of potential participants were received of whom 319 were eligible and 166 agreed to take part, 99 randomly assigned to receive gFNP and 67 to usual care. There were no between-arm differences in AAPI-2 total (7 · 5/10 in both, SE 0.1), difference adjusted for baseline, site and maternal age group 0 · 06 (95% CI − 0 · 15 to 0 · 28, p = 0 · 59) or CARE Index (intervention 4 · 0 (SE 0 · 3); control 4 · 7 (SE 0 · 4); difference adjusted for site and maternal age group − 0 · 68 (95% CI − 1 · 62 to 0 · 16, p = 0 · 25) scores. The probability that gFNP is cost-effective based on the QALY measure did not exceed 3%.

Conclusions

The trial did not support gFNP as a means of reducing the risk of child maltreatment in this population but slow recruitment adversely affected group size and consequently delivery of the intervention.

Group Prenatal Care Results in Medicaid Savings with Better Outcomes: A Propensity Score Analysis of CenteringPregnancy Participation in South Carolina

Objectives This study was undertaken to determine the cost savings of prevention of adverse birth outcomes for Medicaid women participating in the CenteringPregnancy group prenatal care program at a pilot program in South Carolina. Methods A retrospective five-year cohort study of Medicaid women was assessed for differences in birth outcomes among women involved in CenteringPregnancy group prenatal care (n = 1262) and those receiving individual prenatal care (n = 5066). The study outcomes examined were premature birth and the related outcomes of low birthweight (LBW) and neonatal intensive care unit (NICU) visits. Because women were not assigned to the CenteringPregnancy group, a propensity score analysis ensured that the inference of the estimated difference in birth outcomes between the treatment groups was adjusted for nonrandom assignment based on age, race, Clinical Risk Group, and plan type. A series of generalized linear models were run to estimate the difference between the proportions of individuals with adverse birth outcomes, or the risk differences, for CenteringPregnancy group prenatal care participation. Estimated risk differences, the coefficient on the CenteringPregnancy group indicator variable from identity-link binomial variance generalized linear models, were then used to calculate potential cost savings due to participation in the CenteringPregnancy group. Results This study estimated that CenteringPregnancy participation reduced the risk of premature birth (36 %, P < 0.05). For every premature birth prevented, there was an average savings of $22,667 in health expenditures. Participation in CenteringPregnancy reduced the incidence of delivering an infant that was LBW (44 %, P < 0.05, $29,627). Additionally, infants of CenteringPregnancy participants had a reduced risk of a NICU stay (28 %, P < 0.05, $27,249). After considering the state investment of $1.7 million, there was an estimated return on investment of nearly $2.3 million. Conclusions Cost savings were achieved with better outcomes due to the participation in CenteringPregnancy among low-risk Medicaid beneficiaries.

Communication and Exchange of Specialized Health-Related Support Among People With Experiential Similarity on Facebook

Social support is an important factor that shapes how people cope with illness, and health-related communication among peers managing the same illness (network ties with experiential similarity) offers specialized information, resources, and emotional support. Facebook has become a ubiquitous part of many Americans' lives, and may offer a way for patients and caregivers experiencing a similar illness to exchange specialized health-related support. However, little is known about the content of communication among people who have coped with the same illness on personal Facebook pages. We conducted a content analysis of 12 months of data from 18 publicly available Facebook pages hosted by parents of children with acute lymphoblastic leukemia, focusing on communication between users who self-identified as parents of pediatric cancer patients. Support exchanges between users with experiential similarity contained highly specialized health-related information, including information about health services use, symptom recognition, compliance, medication use, treatment protocols, and medical procedures. Parents also exchanged tailored emotional support through comparison, empathy, encouragement, and hope. Building upon previous research documenting that social media use can widen and diversify support networks, our findings show that cancer caregivers access specialized health-related informational and emotional support through communication with others who have experienced the same illness on personal Facebook pages. These findings have implications for health communication practice and offer evidence to tailor M-Health interventions that leverage existing social media platforms to enhance peer support for patients and caregivers.

A systematic overview of the literature regarding group prenatal care for high-risk pregnant women

BACKGROUND

Group prenatal care (GPC) models have been gaining popularity in recent years. Studies of high-risk groups have shown improved outcomes. Our objective was to review and summarize outcomes for women in GPC for women with specific high-risk conditions.

METHODS

A systematic literature review of Ovid, PubMed, and Google Scholar was performed to identify studies reporting the effects of group prenatal care in high-risk populations. Studies were included if they reported on pregnancy outcome results for women using GPC. We also contacted providers known to be utilizing GPC for specific high-risk women. Descriptive results were compiled and summarized by high-risk population.

RESULTS

We identified 37 reports for inclusion (8 randomized trials, 23 nonrandomized studies, 6 reports of group outcomes without controls). Preterm birth was found to be decreased among low-income and African American women. Attendance at prenatal visits was shown to increase among women in GPC in the following groups: Opioid Addiction, Adolescents, and Low-Income. Improved weight trajectories and compliance with the IOM's weight recommendations were found in adolescents. Increased rates of breastfeeding were found in adolescents and African Americans. Increased satisfaction with care was found in adolescents and African Americans. Pregnancy knowledge was increased among adolescents, as was uptake of LARC. Improved psychological outcomes were found among adolescents and low-income women. Studies in women with diabetes demonstrated that fewer women required treatment with medication when exposed to GPC, and for those requiring treatment with insulin, GPC individuals required less than half the dose. Among women with tobacco use, those who had continued to smoke after finding out they were pregnant were 5 times more likely to quit later in pregnancy if they were engaged in GPC.

CONCLUSIONS

Several groups of high-risk pregnant women may have benefits from engaging in group prenatal care. Because there is a paucity of high-quality, well-controlled studies, more trials in high-risk women are needed to determine whether it improves outcomes and costs of pregnancy-related care.

An evaluation of Interprofessional group antenatal care: a prospective comparative study

Background

Maternal and neonatal outcomes are influenced by the nature of antenatal care. Standard pregnancy care is provided on an individual basis, with one-on-one appointments between a client and family doctor, midwife or obstetrician. A novel, group-based antenatal care delivery model was developed in the United States in the 1990s and is growing in popularity beyond the borders of the USA. The purpose of this study was to evaluate outcomes in clients receiving interprofessional group perinatal care versus interprofessional individual care in a Canadian setting.

Methods

Clients attending the South Community Birth Program (SCBP), an interprofessional, collaborative, primary care maternity program, offering both individual and group care, were invited to participate in the study. Pregnancy knowledge and satisfaction scores, and perinatal outcomes were compared between those receiving group versus individual care. Chi-square tests, general linear models and logistic regression were used to compare the questionnaire scores and perinatal outcomes between cohorts.

Results

Three hundred three clients participated in the study. Group care was comparable to individual care in terms of mode of birth, gestational age at birth, infant birth weight, breastfeeding rates, pregnancy knowledge, preparedness for labour and baby care, and client satisfaction. The rates of adverse perinatal outcomes were extremely low amongst SCBP clients, regardless of the type of care received (preterm birth rates ~5%). Breastfeeding rates were very high amongst all study participants (> 78% exclusive breastfeeding), as were measures of pregnancy knowledge and satisfaction.

Conclusions

This is the first Canadian study to compare outcomes in clients receiving interprofessional group care versus individual care. Our observation that interprofessional group care outcomes and satisfaction were as good as interprofessional individual care has important implications for the antenatal care of clients and for addressing the projected maternity provider crisis facing Canada, particularly in small and rural communities. Further study of group-based care including not only client satisfaction, but also provider satisfaction, is needed. In addition, research into the role of interprofessional care in meeting the needs and improving perinatal outcomes of different populations is necessary.

Diagnosis of Pregnancy and Providing Options Counseling for the Adolescent Patient

The American Academy of Pediatrics policy statement "Options Counseling for the Pregnant Adolescent Patient" recommends the basic content of the pediatrician's counseling for an adolescent facing a new diagnosis of pregnancy. However, options counseling is just one aspect of what may be one of the more challenging scenarios in the pediatric office. Pediatricians must remain alert to the possibility of pregnancy among their adolescent female patients. When discovering symptoms suggestive of pregnancy, pediatricians must obtain a relevant history, perform diagnostic testing and properly interpret the results, and understand the significance of the results from the patient perspective and reveal them to the patient in a sensitive manner. If the patient is indeed pregnant, the pediatrician, in addition to providing comprehensive options counseling, may need to help recruit adult support for the patient and should offer continued assistance to the adolescent and her family after the office visit. All pediatricians should be aware of the legal aspects of adolescent reproductive care and the resources for pregnant adolescents in their communities. This clinical report presents a more comprehensive view of the evaluation and management of pregnancy in the adolescent patient and a context for options counseling.

Maternal distress in late pregnancy alters obstetric outcomes and the expression of genes important for placental glucocorticoid signalling

The experience of maternal distress in pregnancy is often linked with poorer obstetric outcomes for women as well as adverse outcomes for offspring. Alterations in placental glucocorticoid signalling and subsequent increased fetal exposure to cortisol have been suggested to underlie this relationship. In the current study, 121 pregnant women completed the Perceived Stress Scale, State Trait Anxiety Inventory and Edinburgh Postnatal Depression Scale in the third trimester of pregnancy. Placental samples were collected after delivery. Maternal history of psychiatric illness and miscarriage were significant predictors of poorer mental health in pregnancy. Higher anxiety was associated with an increase in women delivering via elective Caesarean Section, and an increase in bottle-feeding. Birth temperature was mildly reduced among infants of women with high levels of depressive symptomology. Babies of mothers who scored high in all stress (cumulative distress) measures had reduced 5-min Apgar scores. High cumulative distress reduced the expression of placental HSD11B2 mRNA and increased the expression of placental NR3C1 mRNA. These data support a role for prenatal distress as a risk factor for altered obstetric outcomes. The alterations in placental gene expression support a role for altered placental glucocorticoid signalling in the relationship between maternal prenatal distress and adverse outcomes.

Group based learning among caregivers: assessing mothers' knowledge before and after an early childhood intervention in rural Guatemala

BACKGROUND

The first three years of a child's life are a critical period for brain growth and development. Caregiver interventions during this period that improve early childhood health and development have the potential to enhance a child's physical, mental, and social well-being.

METHODS

This was a pretest/posttest quasi experimental program evaluation. Early childhood education materials were adapted to create two separate interventions consisting of 30-page interactive flipchart talks to educate mothers on health and development topics relevant to 0-6 and 6-12 month old children. Three community health workers performed the talks with groups of 5-8 mothers. Short learning assessments were given individually to each mother pre-intervention (pretest), immediately post-intervention (posttest 1), and two weeks post-intervention (posttest 2). Demographic surveys and focus group discussions were conducted with all participants.

RESULTS

Mothers (n = 77) had an average age of 33.6 years and had an average of 3.6 living children. Most of the mothers (71%) had received some primary education, but 23% had received no formal schooling. For the 0-6 months flipchart learning assessment (n = 38), the mean pretest score was 77% correct. The mean posttest 1 score improved to 87% (p < 0.0001), and the mean posttest 2 score improved further from the mean posttest 1 score to 90% (p = 0.01). For the 6-12 months flipchart learning assessment (n = 39), the mean pretest score was 78%. The mean posttest 1 score improved to 89% (p < 0.0001), and the mean posttest 2 score improved further from the mean posttest 1 score to 92% (p = 0.03).

CONCLUSIONS

Mothers in an impoverished region of southwestern Guatemala significantly increased their knowledge about child health topics following a short interactive group talk. Mothers further increased their knowledge two weeks after the intervention, without specific re-exposure to the intervention materials, suggesting assimilation and informal reinforcement through group based learning with other mothers in their community.

Prenatal Breastfeeding Education: Impact on Infants With Neonatal Abstinence Syndrome

BACKGROUND

Neonatal abstinence syndrome (NAS) is a growing problem in the United States, affecting 32,000 infants annually. Although breastfeeding would benefit infants with NAS, rates among these mothers are low.

PURPOSE

The purpose of this quality improvement project was to increase breastfeeding rates and decrease hospital length of stay (LOS) for infants with NAS through prenatal breastfeeding initiatives.

METHOD

A pre-/postquality improvement design was used to assess the relationship between breastfeeding initiatives on breastfeeding rates and LOS in infants with NAS. A 3-class curriculum was offered to pregnant women at risk for delivering an infant with NAS. Chart review was completed for all infants evaluated for NAS in a hospital at baseline (n = 56), after Baby Friendly Status (BFS) (n = 75), and after BFS plus breastfeeding education (n = 69).

RESULTS

Although not statistically significant, the BFS plus breastfeeding education cohort had the largest percentage of exclusively breastfed infants during hospitalization (24.6%) and at discharge (31.9%). There was a statistically significant decrease in LOS (P < .001) between cohorts.

IMPLICATIONS FOR PRACTICE

The small sample made it not possible to infer direct impact of the intervention. However, results suggest that prenatal education may contribute to an increase in the numbers of infants with NAS who receive human milk and a decrease in hospital LOS.

IMPLICATION FOR RESEARCH

Refinement of best practices around breastfeeding education and support for mothers at risk of delivering an infant with NAS is recommended so that breastfeeding may have the greatest impact for this subgroup of women and their infants.

Maternal socioeconomic disadvantage is associated with transcriptional indications of greater immune activation and slower tissue maturation in placental biopsies and newborn cord blood

Children from economically disadvantaged families experience worse cognitive, psychiatric, and medical outcomes compared to more affluent youth. Preclinical models suggest some of the adverse influence of disadvantage could be transmitted during gestation via maternal immune activation, but this hypothesis has not been tested in humans. It also remains unclear whether prenatal interventions can mitigate such effects. To fill these gaps, we conducted two studies. Study 1 characterized the socioeconomic conditions of 79 women during pregnancy. At delivery, placenta biopsies and umbilical blood were collected for transcriptional profiling. Maternal disadvantage was associated with a transcriptional profile indicative of higher immune activation and slower fetal maturation, particularly in pathways related to brain, heart, and immune development. Cord blood cells of disadvantaged newborns also showed indications of immaturity, as reflected in down-regulation of pathways that coordinate myeloid cell development. These associations were independent of fetal sex, and characteristics of mothers (age, race, adiposity, diabetes, pre-eclampsia) and babies (delivery method, gestational age). Study 2 performed the same transcriptional analyses in specimens from 20 women participating in CenteringPregnancy, a group-based psychosocial intervention, and 20 women in traditional prenatal care. In both placenta biopsies and cord blood, women in CenteringPregnancy showed up-regulation of transcripts found in Study 1 to be most down-regulated in conjunction with disadvantage. Collectively, these results suggest socioeconomic disparities in placental biology are evident at birth, and provide clues about the mechanistic origins of health disparities. They also suggest the possibility that psychosocial interventions could have mitigating influences.

Exploring the social determinants of racial/ethnic disparities in prenatal care utilization and maternal outcome

Rates of maternal morbidity and mortality are rising in the United States. Non-Hispanic Black women are at highest risk for these outcomes compared to those of other race/ethnicities. Black women are also more likely to be late to prenatal care or be inadequate users of prenatal care. Prenatal care can engage those at risk and potentially influence perinatal outcomes but further research on the link between prenatal care and maternal outcomes is needed. The objective of this article is to review literature illuminating the relationship between prenatal care utilization, social determinants of health, and racial disparities in maternal outcome. We present a theoretical framework connecting the complex factors that may link race, social context, prenatal care utilization, and maternal morbidity/mortality. Prenatal care innovations showing potential to engage with the social determinants of maternal health and address disparities and priorities for future research are reviewed.

'To be able to support her, I must feel calm and safe': pregnant women's partners perceptions of professional support during pregnancy

Background

Professional support does not always meet the needs of expectant fathers or co-mothers. The way in which professional support is offered during pregnancy varies internationally, depending on the country. In order to attain a greater understanding of partners’ experiences of professional support, it is necessary to further illuminate their perceptions of it. The aim of this study was therefore to explore pregnant women’s partners’ perceptions of professional support during pregnancy.

Methods

Qualitative research design. Partners of pregnant women were interviewed during gestational week 36–38. Individual semi-structured interviews were used to explore the partners’ perceptions. The data was analysed using a phenomenographic approach. The study was performed in a county in south-western Sweden; the data collection was conducted from November 2014 to February 2015. Fourteen partners (expectant fathers and co-mothers) of women who were expectant first-time mothers with singleton pregnancies, were interviewed.

Results

The findings of the study are presented through four descriptive categories: Ability to absorb adequate information; Possibility to meet and share with other expectant parents; Confirmation of the partner’s importance; and Influence on the couple relationship. Using a theoretical assumption of the relationship between the categories showed that the fourth category was influenced by the other three categories.

Conclusions

The partners perceived that professional support during pregnancy could influence the couple relationship. The partners’ ability to communicate and to experience togetherness with the women increased when the expectant couple received professional support together. The support created also possibilities to meet and share experiences with other expectant parents. In contrast, a lack of support was found to contribute to partners’ feelings of unimportance. It was essential that the midwives included the partners by confirming that they were individuals who had different needs for various types of professional support. The partners perceived it easier to absorb information when it was adequate and given with a pedagogic that made the partners become interested and emotionally engaged.

Improving health literacy through group antenatal care: a prospective cohort study

BACKGROUND

To examine whether exposure to group antenatal care increased women's health literacy by improving their ability to interpret and utilize health messages compared to women who received standard, individual antenatal care in Ghana.

METHODS

We used a prospective cohort design. The setting was a busy urban district hospital in Kumasi, the second most populous city in Ghana. Pregnant women (N = 240) presenting for their first antenatal visit between 11 and 14 weeks gestation were offered participation in the study. A 27% drop-out rate was experienced due to miscarriage, transfer or failure to return for follow-up visits, leaving 184 women in the final sample. Data were collected using an individual structured survey and medical record review. Summary statistics as well as two sample t-tests or chi-square were performed to evaluate the group effect.

RESULTS

Significant group differences were found. Women participating in group care demonstrated improved health literacy by exhibiting a greater understanding of how to operationalize health education messages. There was a significant difference between women enrolled in group antenatal care verses individual antenatal care for preventing problems before delivery, understanding when to access care, birth preparedness and complication readiness, intent to use a modern method of family planning postpartum, greater understanding of the components of breastfeeding and lactational amenorrhea for birth spacing, and intent for postpartum follow-up.

CONCLUSION

Group antenatal care as compared to individual care offers an opportunity to increase quality of care and improve maternal and newborn outcomes. Group antenatal care holds the potential to increase healthy behaviors, promote respectful maternity care, and generate demand for services. Group ANC improves women's health literacy on how to prevent and recognize problems, prepare for delivery, and care for their newborn.

Group versus traditional prenatal care in low-risk women delivering at term: a retrospective cohort study

OBJECTIVE

Group prenatal care (GC) models are receiving increasing attention as a means of preventing preterm birth; yet, there are limited data on whether group care improves perinatal outcomes in women who deliver at term. The purpose of this study was to evaluate our institutional experience with GC over the past decade and test the hypothesis that GC, compared with traditional individual care (TC), improves perinatal outcomes in women who deliver at term.

STUDY DESIGN

We performed a retrospective cohort study of women delivering at term who participated in GC compared with TC. A group of 207 GC patients who delivered at term from 2004 to 2014 were matched in a 1:2 ratio to 414 patients with term singleton pregnancies who delivered at our institution during the same period by delivery year, maternal age, race and insurance status. The primary outcome was low birth weight (<2500 g). Secondary outcomes included early term birth (37.0 to 38 6/7 weeks), 5 min APGAR score <7, special care nursery admission, neonatal intensive care unit (NICU) admission, neonatal demise, cesarean section and number of prenatal visits. Outcomes were compared between the two groups using univariable statistics.

RESULTS

Baseline characteristics were similar between the two matched groups. GC was associated with a significant reduction in low birth weight infants compared with TC (11.1% vs 19.6%; relative risk (RR) 0.57; 95% confidence interval (CI) 0.37 to 0.87). Patients in GC were significantly less likely than controls to require cesarean delivery, have low 5 min APGAR scores and need higher-level neonatal care (NICU: 1.5% vs 6.5%; RR 0.22; 95% CI 0.07 to 0.72). There were no significant differences in rates of early term birth and neonatal demise.

CONCLUSIONS

Low-risk women participating in GC and delivering at term had a lower risk of low birth weight and other adverse perinatal outcomes compared with women in TC. This suggests GC is a promising alternative to individual prenatal care to improve perinatal outcomes in addition to preterm birth.

Association of Group Prenatal Care With Gestational Weight Gain

OBJECTIVE

To compare gestational weight gain among women in group prenatal care with that of women in individual prenatal care.

METHODS

In this retrospective cohort study, women who participated in group prenatal care from 2009 to 2015 and whose body mass indexes (BMIs) and gestational weight gain were recorded were matched with the next two women who had the same payer type, were within 2-kg/m prepregnancy BMI and 2-week gestational age at delivery, and had received individual prenatal care. Bivariate comparisons of demographics and antenatal complications were performed for women in group and individual prenatal care, and weight gain was categorized as "below," "met," or "exceeded" goals according to the 2009 Institute of Medicine guidelines. Logistic regression analysis estimated the association between excessive weight gain and model of care, with adjustment for confounders, stratified by BMI.

RESULTS

Women in group prenatal care (n=2,117) were younger and more commonly non-Hispanic black, nulliparous, and without gestational diabetes (P≤.005 for all). Women in group prenatal care more commonly exceeded the weight gain goals (55% compared with 48%, P<.001). The differences in gestational weight gain were concentrated among normal-weight (mean 34.2 compared with 32.1 pounds, P<.001; 47% compared with 41% exceeded, P=.008) and overweight women (mean 31.5 compared with 27.1 pounds, P<.001; 69% compared with 54% exceeded, P<.001). When adjusted for age, race-ethnicity, parity, education, and tobacco use, the increased odds for excessive gestational weight gain persisted among normal-weight (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.09-1.51) and overweight (OR 1.84, 95% CI 1.50-2.27) women. Nulliparity was associated with increased excessive gestational weight gain (OR 1.49, 95% CI 1.33-1.68), whereas Hispanic ethnicity was associated with decreased excessive gestational weight gain (OR 0.68, 95% CI 0.59-0.78).

CONCLUSION

Among normal-weight or overweight women, group prenatal care, compared with individual prenatal care, is associated with excessive gestational weight gain.

Bridging Income Generation with Group Integrated Care for cardiovascular risk reduction: Rationale and design of the BIGPIC study

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of mortality worldwide, with >80% of CVD deaths occurring in low and middle income countries (LMICs). Diabetes mellitus and pre-diabetes are risk factors for CVD, and CVD is the major cause of morbidity and mortality among individuals with DM. There is a critical period now during which reducing CVD risk among individuals with diabetes and pre-diabetes may have a major impact. Cost-effective, culturally appropriate, and context-specific approaches are required. Two promising strategies to improve health outcomes are group medical visits and microfinance.

METHODS/DESIGN

This study tests whether group medical visits integrated into microfinance groups are effective and cost-effective in reducing CVD risk among individuals with diabetes or at increased risk for diabetes in western Kenya. An initial phase of qualitative inquiry will assess contextual factors, facilitators, and barriers that may impact integration of group medical visits and microfinance for CVD risk reduction. Subsequently, we will conduct a four-arm cluster randomized trial comparing: (1) usual clinical care, (2) usual clinical care plus microfinance groups only, (3) group medical visits only, and (4) group medical visits integrated into microfinance groups. The primary outcome measure will be 1-year change in systolic blood pressure, and a key secondary outcome measure is 1-year change in overall CVD risk as measured by the QRISK2 score. We will conduct mediation analysis to evaluate the influence of changes in social network characteristics on intervention outcomes, as well as moderation analysis to evaluate the influence of baseline social network characteristics on effectiveness of the interventions. Cost-effectiveness analysis will be conducted in terms of cost per unit change in systolic blood pressure, percent change in CVD risk score, and per disability-adjusted life year saved.

DISCUSSION

This study will provide evidence regarding effectiveness and cost-effectiveness of interventions to reduce CVD risk. We aim to produce generalizable methods and results that can provide a model for adoption in low-resource settings worldwide.

Group prenatal care

Patients participating in group prenatal care gather together with women of similar gestational ages and 2 providers who cofacilitate an educational session after a brief medical assessment. The model was first described in the 1990s by a midwife for low-risk patients and is now practiced by midwives and physicians for both low-risk patients and some high-risk patients, such as those with diabetes. The majority of literature on group prenatal care uses CenteringPregnancy, the most popular model. The first randomized controlled trial of CenteringPregnancy showed that it reduced the risk of preterm birth in low-risk women. However, recent meta-analyses have shown similar rates of preterm birth, low birthweight, and neonatal intensive care unit admission between women participating in group prenatal care and individual prenatal care. There may be subgroups, such as African Americans, who benefit from this type of prenatal care with significantly lower rates of preterm birth. Group prenatal care seems to result in increased patient satisfaction and knowledge and use of postpartum family planning as well as improved weight gain parameters. The literature is inconclusive regarding breast-feeding, stress, depression, and positive health behaviors, although it is theorized that group prenatal care positively affects these outcomes. It is unclear whether group prenatal care results in cost savings, although it may in large-volume practices if each group consists of approximately 8-10 women. Group prenatal care requires a significant paradigm shift. It can be difficult to implement and sustain. More randomized trials are needed to ascertain the true benefits of the model, best practices for implementation, and subgroups who may benefit most from this innovative way to provide prenatal care. In short, group prenatal care is an innovative and promising model with comparable pregnancy outcomes to individual prenatal care in the general population and improved outcomes in some demographic groups.

Expect With Me: development and evaluation design for an innovative model of group prenatal care to improve perinatal outcomes

BACKGROUND

Despite biomedical advances and intervention efforts, rates of preterm birth and other adverse outcomes in the United States have remained relatively intransigent. Evidence suggests that group prenatal care can reduce these risks, with implications for maternal and child health as well as substantial cost savings. However, widespread dissemination presents challenges, in part because training and health systems have not been designed to deliver care in a group setting. This manuscript describes the design and evaluation of Expect With Me, an innovative model of group prenatal care with a strong integrated information technology (IT) platform designed to be scalable nationally.

METHODS/DESIGN

Expect With Me follows clinical guidelines from the American Congress of Obstetricians and Gynecologists. Expect With Me incorporates the best evidence-based features of existing models of group care with a novel integrated IT platform designed to improve patient engagement and support, enhance health behaviors and decision making, connect providers and patients, and improve health service delivery. A multisite prospective longitudinal cohort study is being conducted to examine the impact of Expect With Me on perinatal and postpartum outcomes, and to identify and address barriers to national scalability. Process and outcome evaluation will include quantitative and qualitative data collection at patient, provider, and organizational levels. Mixed-method data collection includes patient surveys, medical record reviews, patient focus groups; provider surveys, session evaluations, provider focus groups and in-depth interviews; an online tracking system; and clinical site visits. A two-to-one matched cohort of women receiving individual care from each site will provide a comparison group (n = 1,000 Expect With Me patients; n = 2,000 individual care patients) for outcome and cost analyses.

DISCUSSION

By bundling prevention and care services into a high-touch, high-tech group prenatal care model, Expect With Me has the potential to result in fundamental changes to the health care system to meet the "triple aim:" better healthcare quality, improved outcomes, and lower costs. Findings from this study will be used to optimize the dissemination and effectiveness of this model.

Centering and Racial Disparities (CRADLE study): rationale and design of a randomized controlled trial of centeringpregnancy and birth outcomes

Background

In the United States, preterm birth (PTB) before 37 weeks gestational age occurs at an unacceptably high rate, and large racial disparities persist. To date, medical and public health interventions have achieved limited success in reducing rates of PTB. Innovative changes in healthcare delivery are needed to improve pregnancy outcomes. One such model is CenteringPregnancy group prenatal care (GPNC), in which individual physical assessments are combined with facilitated group education and social support. Most existing studies in the literature on GPNC are observational. Although the results are promising, they are not powered to detect differences in PTB, do not address the racial disparity in PTB, and do not include measures of hypothesized mediators that are theoretically based and validated. The aims of this randomized controlled trial (RCT) are to compare birth outcomes as well as maternal behavioral and psychosocial outcomes by race among pregnant women who participate in GPNC to their counterparts in individual prenatal care (IPNC) and to investigate whether improving women’s behavioral and psychosocial outcomes will explain the potential benefits of GPNC on birth outcomes and racial disparities.

Methods/design

This is a single site RCT study at Greenville Health System in South Carolina. Women are eligible if they are between 14–45 years old and enter prenatal care before 20 6/7 weeks of gestational age. Eligible, consenting women will be randomized 1:1 into GPNC group or IPNC group, stratified by race. Women allocated to GPNC will attend 2-h group prenatal care sessions according to the standard curriculum provided by the Centering Healthcare Institute, with other women due to deliver in the same month. Women allocated to IPNC will attend standard, traditional individual prenatal care according to standard clinical guidelines. Patients in both groups will be followed up until 12 weeks postpartum.

Discussion

Findings from this project will provide rigorous scientific evidence on the role of GPNC in reducing the rate of PTB, and specifically in reducing racial disparities in PTB. Establishing the improved effect of GPNC on pregnancy and birth outcomes can change the way healthcare is delivered, particularly with populations with higher rates of PTB.

Depressive symptoms and gestational length among pregnant adolescents: Cluster randomized control trial of CenteringPregnancy® plus group prenatal care

OBJECTIVES

Depressive symptoms are associated with preterm birth among adults. Pregnant adolescents have high rates of depressive symptoms and low rates of treatment; however, few interventions have targeted this vulnerable group. Objectives are to: (a) examine impact of CenteringPregnancy® Plus group prenatal care on perinatal depressive symptoms compared to individual prenatal care; and (b) determine effects of depressive symptoms on gestational age and preterm birth among pregnant adolescents.

METHOD

This cluster-randomized controlled trial was conducted in 14 community health centers and hospitals in New York City. Clinical sites were randomized to receive standard individual prenatal care (n = 7) or CenteringPregnancy® Plus group prenatal care (n = 7). Pregnant adolescents (ages 14-21, N = 1,135) completed the Center for Epidemiologic Studies Depression Scale during pregnancy (second and third trimesters) and postpartum (6 and 12 months). Gestational age was obtained from medical records, based on ultrasound dating. Intention to treat analyses were used to examine objectives.

RESULTS

Adolescents at clinical sites randomized to CenteringPregnancy® Plus experienced greater reductions in perinatal depressive symptoms compared to those at clinical sites randomized to individual care (p = .003). Increased depressive symptoms from second to third pregnancy trimester were associated with shorter gestational age at delivery and preterm birth (<37 weeks gestation). Third trimester depressive symptoms were also associated with shorter gestational age and preterm birth. All p < .05.

CONCLUSIONS

Pregnant adolescents should be screened for depressive symptoms prior to third trimester. Group prenatal care may be an effective nonpharmacological option for reducing depressive symptoms among perinatal adolescents. (PsycINFO Database Record

Achieving higher-value obstetrical care

Obstetrical care in the United States is unnecessarily costly. Birth is 1 of the most common reasons for healthcare use in the United States and 1 of the top expenditures for payers every year. However, compared with other Organization for Economic Cooperation and Development countries, the United States spends substantially more money per birth without better outcomes. Our team at the Clinical Excellence Research Center, a center that is focused on improving value in healthcare, spent a year studying ways in which obstetrical care in the United States can deliver better outcomes at a lower cost. After a thoughtful discovery process, we identified ways that obstetrical care could be delivered with higher value. In this article, we recommend 3 redesign steps that foster the delivery of higher-value maternity care: (1) to provide long-acting reversible contraception immediately after birth, (2) to tailor prenatal care according to women's unique medical and psychosocial needs by offering more efficient models such as fewer in-person visits or group care, and (3) to create hospital-affiliated integrated outpatient birth centers as the planned place of birth for low-risk women. For each step, we discuss the redesign concept, current barriers and implementation solutions, and our estimation of potential cost-savings to the United States at scale. We estimate that, if this model were adopted nationally, annual US healthcare spending on obstetrical care would decline by as much as 28%.

Improved Infant Outcomes with Group Prenatal Care in Puerto Rico

OBJECTIVES

To evaluate the impact of group prenatal care (Centering Pregnancy) on the rate of Preterm Birth (PTB) and low birth weight. Women were enrolled into Centering Pregnancy (Transformación Prenatal) if they fell in the category of poverty, and had at least one risk for PTB according to known risk factors for low birth weight or PTB.

METHODS

Mother's age, parity, risk factors, prenatal/delivery complications, infants' Gestational Age (GA), birth weight, Apgar scores, delivery route, indications for delivery, and use of Neonatal Intensive Care Unit (NICU) were abstracted from charts of mothers who received group or traditional care at the University Hospital in San Juan, PR.

RESULTS

More infants were born at term if the mothers received Centering Pregnancy. The mean birth weight and gestational age of the infants were higher (6.59 vs. 6.33 lbs. and 37.8 vs. 36.8 weeks) than for those in traditional care. Centering Pregnancy also had lower rates of preterm birth (27.7% vs. 34.1%) and births earlier than 31 weeks (2.8% vs. 9.9%). All were statistically significant (P<0.05).

CONCLUSIONS

We successfully implemented group prenatal care (Centering Pregnancy) for the first time in PR in a complex environment: tertiary care hospital with a high-risk prenatal clinic. Despite having known risk factors for preterm birth, the mothers in Centering Pregnancy had better outcomes. In an environment of adverse determinants of health, the program was effective in reducing the odds for adverse infant outcomes early in life and demonstrating that innovative models of health care can improve such outcomes.

Systematic Review of Evidence for Baby-Friendly Hospital Initiative Step 3

BACKGROUND

The Ten Steps to Successful Breastfeeding outline maternity practices that protect, promote, and support breastfeeding and serve as the foundation for the Baby-Friendly Hospital Initiative. Research aim: This systematic review describes interventions related to Step 3 of the Ten Steps, which involves informing pregnant women about the benefits and management of breastfeeding. Our main objective was to determine whether prenatal clinic- or hospital-based breastfeeding education increases breastfeeding initiation, duration, or exclusivity.

METHODS

The electronic databases MEDLINE and CINAHL were searched for peer-reviewed manuscripts published in English between January 1, 2000, and May 5, 2016. Bibliographies of relevant systematic reviews were also screened to identify potential studies.

RESULTS

Thirty-eight studies were included. The research studies were either randomized controlled trials or quasi-experimental studies conducted in developed or developing countries. Findings suggest that prenatal interventions, delivered alone or in combination with intrapartum and/or postpartum components, are effective at increasing breastfeeding initiation, duration, or exclusivity where they combine both education and interpersonal support and where women's partners or family are involved. However, varying study quality and lack of standardized assessment of participants' breastfeeding intentions limited the ability to recommend any single intervention as most effective.

CONCLUSION

Future studies should test the strength of maternal breastfeeding intentions, assess the role of family members in influencing breastfeeding outcomes, compare the effectiveness of different health care providers, and include more explicit detail about the time and full cost of different interventions.

Promoting improved social support and quality of life with the CenteringPregnancy® group model of prenatal care

This prospective cohort study compared women participating in CenteringPregnancy® group prenatal care (N = 120) with those in standard individual care (N = 221) to determine if participation in Centering was associated with improvements in perceived social support and quality of life, with concomitant decreases in screens of postpartum depression and improvements in breastfeeding rates. Participants completed surveys at the onset of prenatal care, in the late third trimester and in the postpartum period. Centering participants had higher scores of perceived social support from friends after participating in group care (p < 0.05) with associated improvements in quality of life in the psychological and relational domains (p < 0.05) compared to standard care participants who showed higher scores of perceived support from family (p < 0.05) but did not show concomitant improvements in quality of life. This did not translate to any significant difference in scores on postpartum depression screens but was associated with improvements in breastfeeding continuation rates among Centering participants in the postpartum period. This study indicates that Centering care is associated with improved perceptions of peer social support with associated improvements in quality of life and higher rates of continued breastfeeding.

The effectiveness of introducing Group Prenatal Care (GPC) in selected health facilities in a district of Bangladesh: study protocol

BACKGROUND

Despite high rates of antenatal care and relatively good access to health facilities, maternal and neonatal mortality remain high in Bangladesh. There is an immediate need for implementation of evidence-based, cost-effective interventions to improve maternal and neonatal health outcomes. The aim of the study is to assess the effect of the intervention namely Group Prenatal Care (GPC) on utilization of standard number of antenatal care, post natal care including skilled birth attendance and institutional deliveries instead of usual care.

METHODS

The study is quasi-experimental in design. We aim to recruit 576 pregnant women (288 interventions and 288 comparisons) less than 20 weeks of gestational age. The intervention will be delivered over around 6 months. The outcome measure is the difference in maternal service coverage including ANC and PNC coverage, skilled birth attendance and institutional deliveries between the intervention and comparison group.

DISCUSSION

Findings from the research will contribute to improve maternal and newborn outcome in our existing health system. Findings of the research can be used for planning a new strategy and improving the health outcome for Bangladeshi women. Finally addressing the maternal health goal, this study is able to contribute to strengthening health system.

Does breast-feeding reduce offspring junk food consumption during childhood? Examinations by socio-economic status and race/ethnicity

Objective

To examine whether breast-feeding duration and socio-economic status (SES) interact to predict junk food consumption among offspring and whether the interaction differs across racial/ethnic groups.

Design

Survey research using a longitudinal panel design. Hierarchical linear regression was used to analyse the data.

Setting

In-home interviews with the child’s parents over a 5-year period across the USA.

Subjects

Approximately 10 000 American children from the Early Childhood Longitudinal Study: Birth Cohort (ECLS-B).

Results

The findings revealed that longer breast-feeding durations correspond to lower levels of junk food consumption, but that this relationship emerges consistently only among low-SES blacks.

Conclusions

Efforts to promote breast-feeding among low-SES black women may have the added benefit of reducing their children’s junk food intake, and may thereby promote their general health and well-being. Future research should seek to explore the mechanisms by which breast-feeding might benefit the dietary habits of low-SES black children.

Antenatal care trial interventions: a systematic scoping review and taxonomy development of care models

BACKGROUND

Antenatal care models vary widely around the world, reflecting local contexts, drivers and resources. Randomised controlled trials (RCTs) have tested the impact of multi-component antenatal care interventions on service delivery and outcomes in many countries since the 1980s. Some have applied entirely new schemes, while others have modified existing care delivery approaches. Systematic reviews (SRs) indicate that some specific antenatal interventions are more effective than others; however the causal mechanisms leading to better outcomes are poorly understood, limiting implementation and future research. As a first step in identifying what might be making the difference we conducted a scoping review of interventions tested in RCTs in order to establish a taxonomy of antenatal care models.

METHODS

A protocol-driven systematic search was undertaken of databases for RCTs and SRs reporting antenatal care interventions. Results were unrestricted by time or locality, but limited to English language. Key characteristics of both experimental and control interventions in the included trials were mapped using SPIO (Study design; Population; Intervention; Outcomes) criteria and the intervention and principal outcome measures were described. Commonalities and differences between the components that were being tested in each study were identified by consensus, resulting in a comprehensive description of emergent models for antenatal care interventions.

RESULTS

Of 13,050 articles retrieved, we identified 153 eligible articles including 130 RCTs in 34 countries. The interventions tested in these trials varied from the number of visits to the location of care provision, and from the content of care to the professional/lay group providing that care. In most studies neither intervention nor control arm was well described. Our analysis of the identified trials of antenatal care interventions produced the following taxonomy: Universal provision model (for all women irrespective of health state or complications); Restricted 'lower-risk'-based provision model (midwifery-led or reduced/flexible visit approach for healthy women); Augmented provision model (antenatal care as in Universal provision above but augmented by clinical, educational or behavioural intervention); Targeted 'higher-risk'-based provision model (for woman with defined clinical or socio-demographic risk factors). The first category was most commonly tested in low-income countries (i.e. resource-poor settings), particularly in Asia. The other categories were tested around the world. The trials included a range of care providers, including midwives, nurses, doctors, and lay workers.

CONCLUSIONS

Interventions can be defined and described in many ways. The intended antenatal care population group proved the simplest and most clinically relevant way of distinguishing trials which might otherwise be categorised together. Since our review excluded non-trial interventions, the taxonomy does not represent antenatal care provision worldwide. It offers a stable and reproducible approach to describing the purpose and content of models of antenatal care which have been tested in a trial. It highlights a lack of reported detail of trial interventions and usual care processes. It provides a baseline for future work to examine and test the salient characteristics of the most effective models, and could also help decision-makers and service planners in planning implementation.

Effects of Group Prenatal Care on Food Insecurity during Late Pregnancy and Early Postpartum

OBJECTIVE

This study compared the effects of group to individual prenatal care in late pregnancy and early postpartum on (1) women's food security and (2) psychosocial outcomes among food-insecure women.

METHODS AND RESULTS

We recruited 248 racially diverse, low-income, pregnant women receiving CenteringPregnancy™ group prenatal care (N = 124) or individual prenatal care (N = 124) to complete surveys in early pregnancy, late pregnancy, and early postpartum, with 84 % completing three surveys. Twenty-six percent of group and 31 % of individual care participants reported food insecurity in early pregnancy (p = 0.493). In multiple logistic regression models, women choosing group versus individual care were more likely to report food security in late pregnancy (0.85 vs. 0.66 average predicted probability, p < 0.001) and postpartum (0.89 vs. 0.78 average predicted probability, p = 0.049). Among initially food-insecure women, group participants were more likely to become food-secure in late pregnancy (0.67 vs. 0.35 individual care average predicted probability, p < 0.001) and postpartum (0.76 vs. 0.57 individual care average predicted probability, p = 0.052) in intention-to-treat models. Group participants were more likely to change perceptions on affording healthy foods and stretching food resources. Group compared to individual care participants with early pregnancy food insecurity demonstrated higher maternal-infant attachment scale scores (89.8 vs. 86.2 points for individual care, p = 0.032).

CONCLUSIONS

Group prenatal care provides health education and the opportunity for women to share experiences and knowledge, which may improve food security through increasing confidence and skills in managing household food resources. Health sector interventions can complement food assistance programs in addressing food insecurity during pregnancy.

Invested in Success: A Qualitative Study of the Experience of CenteringPregnancy Group Prenatal Care for Perinatal Educators

The objective of this study was to understand the central meaning of the experience of providing CenteringPregnancy for perinatal educators who were facilitators for the group sessions. Four perinatal educators participated in one-on-one interviews and/or a validation focus group. Six themes emerged: (a) "stepping back and taking on a different role," (b) "supporting transformation," (c) "getting to knowing," (d) "working together to bridge the gap," (e) "creating the environment," and (f) "fostering community." These themes contributed to the core phenomenon of being "invested in success." Through bridging gaps and inconsistencies in information received from educators and physicians, this model of CenteringPregnancy provides an opportunity for women to act on relevant information more fully than more traditional didactic approaches to perinatal education.

Design of the integrative medical group visits randomized control trial for underserved patients with chronic pain and depression

BACKGROUND

Given the public health crisis of opioid overprescribing for pain, there is a need for evidence-based non pharmacological treatment options that effectively reduce pain and depression. We aim to examine the effectiveness of the Integrative Medical Group Visits (IMGV) model in reducing chronic pain and depressive symptoms, as well as increasing pain self-management.

METHODS

This paper details the study design and implementation of an ongoing randomized controlled trial of the IMGV model as compared to primary care visits. The research aims to determine if the IMGV model is effective in achieving: a) a reduction in self-reported pain and depressive symptoms and 2) an improvement in the self-management of pain, through increasing pain self-efficacy and reducing use of self-reported pain medication. We intend to recruit 154 participants to be randomized in our intervention, the IMGV model (n=77) and to usual care (n=77).

CONCLUSIONS

Usual care of chronic pain through pharmacological treatment has mixed evidence of efficacy and may not improve quality of life or functional status. We aim to conduct a randomized controlled trial to evaluate the effectiveness of the IMGV model as compared to usual care in reducing self-reported pain and depressive symptoms as well as increasing pain management skills.

The interplay of race, socioeconomic status and neighborhood residence upon birth outcomes in a high black infant mortality community

This study examined the interrelationship of race and socioeconomic status (SES) upon infant birthweight at the individual and neighborhood levels within a Midwestern US county marked by high Black infant mortality. The study conducted a multi-level analysis utilizing individual birth records and census tract datasets from 2010, linked through a spatial join with ArcGIS 10.0. The maternal population of 2861 Black and White women delivering infants in 2010, residing in 57 census tracts within the county, constituted the study samples. The main outcome was infant birthweight. The predictors, race and SES were dichotomized into Black and White, low-SES and higher-SES, at both the individual and census tract levels. A two-part Bayesian model demonstrated that individual-level race and SES were more influential birthweight predictors than community-level factors. Specifically, Black women had 1.6 higher odds of delivering a low birthweight (LBW) infant than White women, and low-SES women had 1.7 higher odds of delivering a LBW infant than higher-SES women. Moderate support was found for a three-way interaction between individual-level race, SES and community-level race, such that Black women achieved equity with White women (4.0% Black LBW and 4.1% White LBW) when they each had higher-SES and lived in a racially congruous neighborhood (e.g., Black women lived in disproportionately Black neighborhood and White women lived in disproportionately White neighborhood). In sharp contrast, Black women with higher-SES who lived in a racially incongruous neighborhood (e.g., disproportionately White) had the worst outcomes (14.5% LBW). Demonstrating the layered influence of personal and community circumstances upon health, in a community with substantial racial disparities, personal race and SES independently contribute to birth outcomes, while environmental context, specifically neighborhood racial congruity, is associated with mitigated health risk.

Using Group Medical Visits With Those Who Have Diabetes: Examining the Evidence

The number of people with diabetes is expected to rise to over 592 million by the year 2035. Past work provides evidence that the conventional method of primary care delivery may not meet many patients' needs. An alternative to the conventional one-on-one appointment is care offered to a group of patients through group medical visits (GMVs). Group medical visits for diabetes have a positive impact on physiologic and self-care outcomes including improved HbA1c, blood pressure control and self-management skills. Less work has examined the impacts of GMVs on systems of care; however, evidence suggests improved primary and secondary prevention strategies and the potential for GMVs to decrease emergency room visits and hospitalizations. Additional work is needed to examine the effect of GMVs on patient reported quality of life, functional health status and cost-savings. Further work is also needed on which patients GMVs work best for and patient barriers to attending GMVs.

Antenatal group consultations: Facilitating patient-patient education

OBJECTIVE

This article investigates the perspectives of pregnant women attending antenatal group consultations to gain their understandings of whether and how peer learning is facilitated in this setting.

METHODS

We conducted semi-structured individual interviews with 16 women who had participated in group consultations at Aarhus University Hospital, Denmark, and analysed the data using qualitative content analysis. Our research design also included observations and patient guest book data.

RESULTS

Women who were pregnant for the first time greatly appreciated the experiential knowledge of multiparous women in the group. Group consultations provided new learning opportunities, as individuals' questions prompted learning within the groups, as well as questions and answers. There was more time for reflection in group consultations than in dyadic communication. Midwives played a key role in facilitating peer learning. Some topics were not deemed appropriate for discussion.

CONCLUSION

Antenatal group consultations can support learning, as individuals participate positively both in their own knowledge acquisition and that of others. We call such peer learning patient-patient education.

PRACTICE IMPLICATIONS

Our study indicates the strengths of group consultations for learning from the perspective of the group members. It highlights how learning may be facilitated in group consultations, and thus has broad practical relevance.

Group based prenatal care in a low-and high risk population in the Netherlands: a study protocol for a stepped wedge cluster randomized controlled trial

BACKGROUND

CenteringPregnancy (CP) is a multifaceted group based care-model integrated in routine prenatal care, combining health assessment, education, and support. CP has shown some positive results on perinatal outcomes. However, the effects are less obvious when limited to the results of randomized controlled trials: as there are few trials and there is a variation in reported outcomes. Furthermore, former research was mostly conducted in the United States of America and in specific (often high risk) populations. Our study aims to evaluate the effects of CP in the Netherlands in a general population of pregnant women (low and high risk). Furthermore we aim to explore the mechanisms leading to the eventual effects by measuring potential mediating factors.

DESIGN

We will perform a stepped wedge cluster randomized controlled trial, in a Western region in the Netherlands. Inclusion criteria are <24 weeks of gestation and able to communicate in Dutch (with assistance). Women in the control period will receive individual care, women in the intervention period (starting at the randomized time-point) will be offered the choice between individual care or CP. Primary outcomes are maternal and neonatal morbidity, retrieved from a national routine database. Secondary outcomes are health behavior, psychosocial outcomes, satisfaction, health care utilization and process outcomes, collected through self-administered questionnaires, group-evaluations and individual interviews. We will conduct intention-to-treat analyses. Also a per protocol analysis will be performed comparing the three subgroups: control group, CP-participants and non-CP-participants, using multilevel techniques to account for clustering effects.

DISCUSSION

This study contributes to the evidence regarding the effect of CP and gives a first indication of the effect and implementation of CP in both low and high-risk pregnancies in a high-income Western society other than the USA. Also, measuring factors that are hypothesized to mediate the effect of CP will enable to explain the mechanisms that lead to effects on maternal and neonatal outcomes.

Interventions for promoting the initiation of breastfeeding

BACKGROUND

Despite the widely documented risks of not breastfeeding, initiation rates remain relatively low in many high-income countries, particularly among women in lower-income groups. In low- and middle-income countries, many women do not follow World Health Organization (WHO) recommendations to initiate breastfeeding within the first hour after birth. This is an update of a Cochrane Review, first published in 2005.

OBJECTIVES

To identify and describe health promotion activities intended to increase the initiation rate of breastfeeding.To evaluate the effectiveness of different types of breastfeeding promotion activities, in terms of changing the number of women who initiate breastfeeding.To evaluate the effectiveness of different types of breastfeeding promotion activities, in terms of changing the number of women who initiate breastfeeding early (within one hour after birth).

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (29 February 2016) and scanned reference lists of all articles obtained.

SELECTION CRITERIA

Randomised controlled trials (RCTs), with or without blinding, of any breastfeeding promotion intervention in any population group, except women and infants with a specific health problem.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial reports for inclusion, extracted data and assessed trial quality. Discrepancies were resolved through discussion and a third review author was involved when necessary. We contacted investigators to obtain missing information.

MAIN RESULTS

Twenty-eight trials involving 107,362 women in seven countries are included in this updated review. Five studies involving 3,124 women did not contribute outcome data and we excluded them from the analyses. The methodological quality of the included trials was mixed, with significant numbers of studies at high or unclear risk of bias due to: inadequate allocation concealment (N = 20); lack of blinding of outcome assessment (N = 20); incomplete outcome data (N = 19); selective reporting (N = 22) and bias from other potential sources (N = 17). Healthcare professional-led breastfeeding education and support versus standard care The studies pooled here compare professional health workers delivering breastfeeding education and support during the prenatal and postpartum periods with standard care. Interventions included promotion campaigns and counselling, and all took place in a formal setting. There was evidence from five trials involving 564 women for improved rates ofbreastfeeding initiation among women who received healthcare professional-led breastfeeding education and support (average risk ratio (RR) 1.43, 95% confidence interval (CI) 1.07 to 1.92; Tau² = 0.07, I² = 62%, low-quality evidence) compared to those women who received standard care. We downgraded evidence due to design limitations and heterogeneity. The outcome of early initiation of breastfeeding was not reported in the studies under this comparison. Non-healthcare professional-led breastfeeding education and support versus standard care There was evidence from eight trials of 5712 women for improved rates of breastfeeding initiation among women who received interventions from non-healthcare professional counsellors and support groups (average RR 1.22, 95% CI 1.06 to 1.40; Tau² = 0.02, I² = 86%, low-quality evidence) compared to women who received standard care. In three trials of 76,373 women, there was no clear difference between groups in terms of the number of women practicing early initiation of breastfeeding (average RR 1.70, 95% CI 0.98 to 2.95; Tau² = 0.18, I² = 78%, very low-quality evidence). We downgraded the evidence for a combination of design limitations, heterogeneity and imprecision (wide confidence intervals crossing the line of no effect). Other comparisonsOther comparisons in this review also looked at the rates of initiation of breastfeeding and there were no clear differences between groups for the following comparisons of combined healthcare professional-led education with peer support or community educator versus standard care (2 studies, 1371 women) or attention control (1 study, 237 women), breastfeeding education using multimedia (a self-help manual or a video) versus routine care (2 studies, 497 women); early mother-infant contact versus standard care (2 studies, 309 women); and community-based breastfeeding groups versus no breastfeeding groups (1 study, 18,603 women). None of these comparisons reported data on early initiation of breastfeeding.

AUTHORS' CONCLUSIONS

This review found low-quality evidence that healthcare professional-led breastfeeding education and non-healthcare professional-led counselling and peer support interventions can result in some improvements in the number of women beginning to breastfeed. The majority of the trials were conducted in the USA, among women on low incomes and who varied in ethnicity and feeding intention, thus limiting the generalisability of these results to other settings.Future studies would ideally be conducted in a range of low- and high-income settings, with data on breastfeeding rates over various timeframes, and explore the effectiveness of interventions that are initiated prior to conception or during pregnancy. These might include well-described interventions, including health education, early and continuing mother-infant contact, and initiatives to help mothers overcome societal barriers to breastfeeding, all with clearly defined outcome measures.

The American College of Nurse-Midwives Clarity in Collaboration Project: Describing Midwifery Care in Interprofessional Collaborative Care Models

In 2014, the American College of Nurse-Midwives (ACNM) launched a project called Clarity in Collaboration to develop data definitions related to midwifery and maternity care delivery processes. These definitions are needed to ensure midwifery care delivered in collaborative care models is accurately and consistently captured in clinical documentation systems, data registries, and systems being developed as part of health care restructuring and payment reform. The Clarity in Collaboration project builds on the efforts of the Women's Health Registry Alliance (WHRA), which was recently established by the American College of Obstetricians and Gynecologists. Clarity in Collaboration mirrored the process used by ReVITALize, WHRA's first maternity data standardization project, which focused on establishing standardized clinical data definitions for obstetrics. The ACNM Clarity in Collaboration project brought together maternity and midwifery care experts to complete a year-long consensus process, including a period of public comment, resulting in development of 20 concept definitions. These definitions can be used to describe midwifery care within the context of collaborative care models. This article provides a summary of the ACNM Clarity in Collaboration process with discussion of implications for maternity data collection.

Prenatal visit utilization and outcomes in pregnant women with type II and gestational diabetes

OBJECTIVE

To investigate the association between the number of prenatal visits (PNVs) and pregnancy outcomes in women with gestational diabetes (GDM) and Type 2 diabetes mellitus (DM).

STUDY DESIGN

A 4-year prospective cohort study of women with GDM and DM and was conducted. Patients ⩾75th percentile for number of PNVs were compared with those ⩽25th percentile. The primary outcomes were large for gestational age (LGA) with birth weight >90% and neonatal intensive care unit (NICU) admission for >24 h. Secondary neonatal outcomes included severe LGA (>95%), shoulder dystocia, hyperbilirubinemia requiring phototherapy, neonatal hypoglycemia, low 5 min APGAR score (<7) and preterm birth (prior to 37 weeks). Secondary maternal outcomes included mean third trimester fasting blood glucose, hemoglobin A1c (Hgb A1c) in labor, preeclampsia, gestational weight gain over Institute of Medicine recommendations, mode of delivery and maternal readmission within 30 days. Logistic regression was used to adjust for maternal race, nulliparity and body mass index.

RESULTS

Of the 305 women, 4 were excluded for unknown number of PNVs. Among the 301 included, the average number of visits was 12. Rates of LGA were similar between the high (28%) compared with low (18%) utilization groups (adjusted odds ratio (aOR) 1.69; 95% confidence interval (CI) 0.81-3.54). The high utilization group was 85% less likely to deliver an infant requiring NICU admission (aOR 0.15; 95% CI 0.04-0.53) and 59% less likely to have a preterm birth (aOR 0.41; 95% CI 0.21-0.80). A time-to-event analysis to account for the fact that patients who delivered earlier had fewer weeks to experience PNVs showed that the risk for NICU admission was still significantly lower in the high PNV utilization group (hazard ratio 0.15; 95% CI 0.04-0.51) after adjusting for confounders in a Cox proportional hazard model. The mean Hgb A1c at the time of delivery was significantly better in the high (6.4%) compared with low (6.9%) utilization groups (P=0.01). There were no differences in other maternal outcomes based on prenatal care utilization.

CONCLUSIONS

Diabetic women with high PNV utilization have better glycemic control in the 3 months prior to delivery and are significantly less likely to deliver preterm infants or infants requiring NICU admission. There may be innovative ways to provide prenatal care for GDM and DM to optimize maternal and neonatal outcomes.

Young women's experiences of expected health behaviors during pregnancy: the importance of emotional support

Young women often have access to fewer resources to make expected behavior changes during pregnancy. This qualitative study aimed to explore the experiences of young pregnant and parenting women regarding behavioral expectations and behavior change during pregnancy. Nine women (aged 15 to 24) participated in individual semistructured photo-elicitation interviews and data was analyzed using qualitative content analysis. The findings of this study suggest that although these young women received informational support throughout their pregnancies, there is a need to integrate emotional support into prenatal care for young pregnant women to facilitate their experience as one of empowerment rather than oppression.

Why Are Half of Women Interested in Participating in Group Prenatal Care?

OBJECTIVE

To determine the likelihood of participating in group prenatal care (GPC) and associated factors among low-risk women receiving traditional prenatal care from obstetricians, family physicians or midwives, and to determine factors associated with likelihood of participating.

METHODS

Prior to completing a self-administered questionnaire, a 2-min compiled video of GPC was shown to pregnant women receiving traditional prenatal care. Data were collected on opinions of current prenatal care, GPC, and demographics. Biologically plausible variables with a p value ≤0.20 were entered in the multivariable logistic regression model and those with a p value <0.05 were retained.

RESULTS

Of 477 respondents, 234 [49.2%, 95% confidence interval (CI) 44.6-53.6%] reported being "definitely" or "probably likely" to participate in GPC. Women were more likely to participate in GPC if they had at least postsecondary education [adjusted odds ratio (aOR) 1.84, 95% CI 1.05-3.24], had not discussed labour with their care provider (aOR 1.67, 95% CI 1.12-2.44), and valued woman-centeredness ("fairly important" aOR 2.81, 95% CI 1.77-4.49; "very important" aOR 4.10, 95% CI 2.45-6.88). Women placed high importance on learning components of GPC. The majority would prefer to be with similar women, especially in age. About two-thirds would prefer to have support persons attend GPC and over half would be comfortable with male partners.

CONCLUSION

Approximately half of women receiving traditional prenatal care were interested in participating in GPC. Our findings will hopefully assist providers interested in optimizing satisfaction with traditional prenatal care and GPC by identifying important elements of each, and thus help engage women to consider GPC.

Impacto de estratégias educacionais no pré-natal de baixo risco: revisão sistemática de ensaios clínicos randomizados

Resumo O objetivo deste estudo foi analisar a partir de uma revisão sistemática o impacto de estratégias educacionais desenvolvidas no pré-natal de baixo risco em resultados obstétricos. Foi feita a busca nas bases de dados PubMed, Medline, SciELO e Lilacs por ensaios clínicos randomizados com os desfechos de nascimento: peso ao nascer, prematuridade e aleitamento materno. Foram utilizados os descritores em combinação: prenatal, antenatal visits, education, health education, pregnancy outcomes, birthweight, prematurity, breastfeeding e randomized clinical trials. Após a avaliação da qualidade, incluiu-se nove estudos. As ações mostraram-se mais eficazes quando estendidas até o período pós-parto. A maior parte delas aconteceu durante as visitas domiciliares e apresentou impacto positivo na prática do aleitamento materno e peso ao nascer. A formação de grupos de gestantes contribuiu para menor prevalência de prematuridade. A amamentação mostrou-se o desfecho mais sensível às estratégias educativas. Práticas educativas durante o pré-natal contribuem para resultados obstétricos favoráveis por minimizarem dúvidas e anseios da mulher durante o processo de gestação, preparando-a para o parto e pós-parto, devendo ser incorporadas no processo de trabalho dos serviços de saúde.

Group Prenatal Care Compared With Traditional Prenatal Care: A Systematic Review and Meta-analysis

OBJECTIVE

To estimate the effect of group prenatal care on perinatal outcomes compared with traditional prenatal care.

DATA SOURCES

We searched MEDLINE through PubMed, EMBASE, Scopus, Cumulative Index of Nursing and Allied Health literature, the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov.

METHODS OF STUDY SELECTION

We searched electronic databases for randomized controlled trials and observational studies comparing group care with traditional prenatal care. The primary outcome was preterm birth. Secondary outcomes were low birth weight, neonatal intensive care unit admission, and breastfeeding initiation. Heterogeneity was assessed using the Q test and I statistic. Pooled relative risks (RRs) and weighted mean differences were calculated using random-effects models.

TABULATIONS, INTEGRATION, AND RESULTS

Four randomized controlled trials and 10 observational studies met inclusion criteria. The rate of preterm birth was not significantly different with group care compared with traditional care (11 studies: pooled rates 7.9% compared with 9.3%, pooled RR 0.87, 95% confidence interval [CI] 0.70-1.09). Group care was associated with a decreased rate of low birth weight overall (nine studies: pooled rate 7.5% group care compared with 9.5% traditional care; pooled RR 0.81, 95% CI 0.69-0.96), but not among randomized controlled trials (four studies: 7.9% group care compared with 8.7% traditional care, pooled RR 0.92, 95% CI 0.73-1.16). There were no significant differences in neonatal intensive care unit admission or breastfeeding initiation.

CONCLUSION

Available data suggest that women who participate in group care have similar rates of preterm birth, neonatal intensive care unit admission, and breastfeeding.

Midwifery-led antenatal care models: mapping a systematic review to an evidence-based quality framework to identify key components and characteristics of care

BACKGROUND

Implementing effective antenatal care models is a key global policy goal. However, the mechanisms of action of these multi-faceted models that would allow widespread implementation are seldom examined and poorly understood. In existing care model analyses there is little distinction between what is done, how it is done, and who does it. A new evidence-informed quality maternal and newborn care (QMNC) framework identifies key characteristics of quality care. This offers the opportunity to identify systematically the characteristics of care delivery that may be generalizable across contexts, thereby enhancing implementation. Our objective was to map the characteristics of antenatal care models tested in Randomised Controlled Trials (RCTs) to a new evidence-based framework for quality maternal and newborn care; thus facilitating the identification of characteristics of effective care.

METHODS

A systematic review of RCTs of midwifery-led antenatal care models. Mapping and evaluation of these models' characteristics to the QMNC framework using data extraction and scoring forms derived from the five framework components. Paired team members independently extracted data and conducted quality assessment using the QMNC framework and standard RCT criteria.

RESULTS

From 13,050 citations initially retrieved we identified 17 RCTs of midwifery-led antenatal care models from Australia (7), the UK (4), China (2), and Sweden, Ireland, Mexico and Canada (1 each). QMNC framework scores ranged from 9 to 25 (possible range 0-32), with most models reporting fewer than half the characteristics associated with quality maternity care. Description of care model characteristics was lacking in many studies, but was better reported for the intervention arms. Organisation of care was the best-described component. Underlying values and philosophy of care were poorly reported.

CONCLUSIONS

The QMNC framework facilitates assessment of the characteristics of antenatal care models. It is vital to understand all the characteristics of multi-faceted interventions such as care models; not only what is done but why it is done, by whom, and how this differed from the standard care package. By applying the QMNC framework we have established a foundation for future reports of intervention studies so that the characteristics of individual models can be evaluated, and the impact of any differences appraised.

Sample size determinations for group-based randomized clinical trials with different levels of data hierarchy between experimental and control arms

We derived sample size formulae for detecting main effects in group-based randomized clinical trials with different levels of data hierarchy between experimental and control arms. Such designs are necessary when experimental interventions need to be administered to groups of subjects whereas control conditions need to be administered to individual subjects. This type of trial, often referred to as a partially nested or partially clustered design, has been implemented for management of chronic diseases such as diabetes and is beginning to emerge more commonly in wider clinical settings. Depending on the research setting, the level of hierarchy of data structure for the experimental arm can be three or two, whereas that for the control arm is two or one. Such different levels of data hierarchy assume correlation structures of outcomes that are different between arms, regardless of whether research settings require two or three level data structure for the experimental arm. Therefore, the different correlations should be taken into account for statistical modeling and for sample size determinations. To this end, we considered mixed-effects linear models with different correlation structures between experimental and control arms to theoretically derive and empirically validate the sample size formulae with simulation studies.

Psychosocial Stress During First Pregnancy Predicts Infant Health Outcomes in the First Postnatal Year

OBJECTIVES

To evaluate the impact of psychosocial stress during pregnancy on infant health outcomes in the first postnatal year.

METHODS

A sample of 3000 women completed a stress inventory (the Psychosocial Hassles Scale) during their third trimester before first childbirth. Infant health outcomes were measured via maternal report at 1, 6 and 12 months postpartum. Poisson regression was used to model the effect of maternal stress during pregnancy on infant health outcomes in the first year, controlling for age, race/ethnicity, education, insurance coverage, marital status, and cigarette smoking during pregnancy.

RESULTS

Women who were younger, minority, unmarried, publicly insured and without a college degree were more likely to report high levels of prenatal stress. High prenatal stress was a significant predictor of maternal reporting of gastrointestinal illness (p < 0.0001), respiratory illness (p = 0.025), and total illness in the first year (p < 0.0001). High prenatal stress was also a significant predictor of urgent care visits (p < 0.0001) and emergency department visits (p = 0.001). It was not a significant predictor of hospitalizations (p = 0.36).

CONCLUSIONS

Maternal prenatal stress is associated with increased maternal reporting of infant illness, as well as increased frequency of both urgent care visits and emergency department visits.
